Model for cover cracking due to rebar corrosion in RC structures

An experimental and numerical study of the pattern of cracking of concrete due to steel reinforcement corrosion

“…The expansion factor f} was taken to be 1.0, as found in the literature [1,2,21], although other studies consider a greater expansion of the oxide [22,23]. For the normal stiffness, a wide range of values are found in the literature: in [2], the bulk modulus of the oxide was taken to be of the same order of magnitude as the bulk modulus of water (around 2 GPa); in [23,24] the elastic modulus was estimated from a combination of analytical models and experiments in which the radial displacement in concrete was measured by image correlation techniques; the values obtained in these two studies are, however, very different: an elastic modulus of 0.14 GPa is reported in [23] for an assumed Poisson's ratio of the rust of 0.2, while the values of the elastic modulus reported in [24] range between 2 and 20 GPa, and no reference to Poisson's ratio was made by the authors.…”

Enhancing sustainability of household water filters by mixing metallic iron with porous materials

“…12 months). Due to the volumetric expansive nature of iron corrosion [26][27][28][29], designing iron filters with long-term adequate permeability is a challenge for the scientific community [30].…”

Analysis of Mechanical Behavior of Corroded Reinforced Concrete Structures

“…18 The ratios of volumetric expansion of different typical oxides with respect to the virgin material given in the literature 19 varies between v rs = 1.7 for FeO and v rs = 6.15 for Fe(OH) 3 3H 2 O. While the value of v rs = 2.0 suggested by Molina et al 16 is frequently used in numerical analysis of corroded concrete, 4,8,[11][12][13][14] Bhargava et al 20 proposed a value of v rs = 3.39357 based on the available published experimental data. In this study, the value of v rs = 2.0 was chosen for all the analyses, except for one analysis in which two values-that is, v rs = 2.0 and 3.4-are used for comparison.…”
